Sprint confirms its HD Voice is incompatible with the iPhone 5
The new, lighter iPhone 5 has a bigger screen, punchier processor, LTE and dual-band WiFi, but if you plan to pick one up for Sprint's network, you can't have it all. Carrier spokesperson Michelle Leff Mermelstein told Phone Scoop that its version of HD Voice will not work on Apple's new wünderphone. While most carriers use WCDMA networks to achieve the greater definition, Sprint uses CDMA 1X Advanced, which unfortunately isn't compatible with the handset. Knowing the feature will be missing prior to launch isn't ideal, but when you're calling your friends to boast about that day-one purchase, a slight drop in clarity isn't likely to kill your geek buzz.
SK Telecom deploys HD Voice over LTE, claims title of world's first
The little blue marble we call Earth is no stranger to HD Voice -- it's been around commercially since Orange debuted the service over its 3G network in Moldova nearly three years ago -- but the technology still hasn't been officially deployed over an LTE network. That is, until SK Telecom launches the service later today. Doing so will allow the South Korean carrier to snag the crown for world's first before Sprint, which recently announced that its network won't have it until later this year. It's a win-win scenario for the company: HD Voice over LTE is meant to vastly improve call quality and reduce latency for the customers, while lessening network strain and offering new revenue-making opportunities for SK Telecom. What about devices? It hasn't announced any brand new smartphones that can take advantage of the service, but the company's ready to pre-load the Samsung Galaxy S III with software that enables HD Voice capability, and is planning to push an update to current owners of the flagship device. If you're the type of person that still makes the occasional call, this kind of progress should come as pleasant news.
Clearer calls with HD Voice on Sprint expected before the year's out
We were pretty impressed with our demo of HD Voice on the HTC EVO 4G LTE earlier in the year, but are still waiting for the feature's launch to test it in real situations. We may not have to wait much longer, though, because according to Phone Scoop, Sprint is aiming to roll out the service by the end of 2012. The carrier's Network Vision architecture upgrade is progressing nicely, a necessity for implementing clearer conversations, although coverage is still patchy. We might see an official launch this year, but HD Voice is unlikely to be widely available on the network or on other devices until well into 2013 and 2014. However, if you happen to be a Sprint customer, HTC EVO 4G LTE owner, connected to the right tower and calling someone that's ticking exactly the same boxes, listen out for that bump in quality as the New Year approaches.
Ears-on with HD Voice on the Sprint HTC EVO 4G LTE
So this definitely isn't your ordinary hands-on -- there's really no way to accurately capture audio coming through the earpiece in a mobile phone -- so, well, we'll just have to use our words. Sprint's just-announced HTC EVO 4G LTE is the first device to feature what the carrier has coined "HD Voice." The smartphone uses dual microphones, along with encoders and decoders to capture and transmit your voice from one equipped device to another -- that's right, for now, you and another caller will both need to be using this specific handset, paired with compatible network access points, which Sprint will begin rolling out shortly as part of its "Network Vision." We know what you're thinking: I don't use my phone as a phone. Sprint claims otherwise, however, saying that the network will handle 500 billion voice minutes this year alone. If you happen to account for any of those calls, there's certainly no harm in sharing your spoken word in 'HD.'We hopped into a steamy sound booth at Sprint's NYC launch event today, speaking to an employee using HD Voice on the LTE EVO. The difference was clear, especially once he turned up the "background noise" on a demo music track, which we couldn't hear at all until the handset was moved within an inch or two of the speaker -- we can only imagine how this will play out on the audibly cluttered streets of New York City, which are definitely suited more for text than voice. The HD Voice experience was the same without any background noise at all, and just as impressive. You'll of course still be susceptible to ambient noise on the listening end -- after all, we needed to be in a near-silent booth to block out the sound around. Stay tuned for more detailed impressions in our full review closer to the device's May 7th pre-order date -- we patiently await an opportunity to listen more closely.
Ericsson delivers HD voice on CDMA, crystal clear calling coming to a network near you
Smartphones continue to improve in the "smart" areas: better screens, faster processors, more memory, etc., but there's not been a lot of innovation in the phone aspect of those devices. HD voice technology can change that, but since its introduction in 2009, hi-fi calling was only available on GSM networks... until now. Ericsson has just made the first HD voice call via CDMA -- made possible by a new Enhanced Variable Rate Codec Narrowband-Wideband (EVRC-NW for the awkward acronym-loving crowd). The codec delivers sound in the 50Hz - 7000Hz range, which makes traditional calls limited to the 300Hz - 3400Hz spectrum sound like they're coming from a drive-thru attendant at your local Mickey D's. So far, the tech's limited to the lab, but here's hoping Ericsson lets it roam free to deliver the dulcet tones of our friends and family sooner rather than later. [Thanks, Fdegir]
Orange HD Voice service and handsets go live in the UK, we go ears-on (video)
(function() { var s = document.createElement('SCRIPT'), s1 = document.getElementsByTagName('SCRIPT')[0]; s.type = 'text/javascript'; s.async = true; s.src = 'http://widgets.digg.com/buttons.js'; s1.parentNode.insertBefore(s, s1); })(); Digg Good news for UK mobile addicts: Orange's long-anticipated HD Voice service has officially made it to the Land of Hope and Glory. Starting today, British customers can pick up a HD Voice-enabled handset -- including the Nokia 5230, X6, E5 and Samsung Omnia Pro at launch -- from Orange, and start buttering their ears with "crystal clear" phone calls while within the carrier's 3G coverage. Prior to the launch, we were fortunate enough to try out the new service on a couple of Nokia E5 prototypes in Piccadilly Circus, and boy, that was some pretty impressive stuff there -- the wider speech bandwidth really added a lot of clarity to the caller's voice, and additionally, the noisy traffic from the caller's end was well suppressed at where it'd otherwise crackle over a normal call. Perhaps the easiest way to put it is that this is much like jumping from a bad FM radio broadcast to some sweet CD audio, thus making conversations a lot easier to interpret, even if the recipient is in a noisy environment or has hearing problem (as proven by Orange's public trial). As always, hearing is believing, so do check out our sample audio clips after the break. While Orange remains a dominant driving force behind this mobile revolution, the carrier assured us that it expects other companies to pick up this open standard. That said, it's rather disappointing that current owners of the aforementioned handsets won't be getting a software patch for the HD upgrade (we were told that no extra hardware is involved), but we can understand -- the manufacturers do need to sell new phones to stay alive in this rapidly changing market. Anyhow, here's hoping that the forthcoming flagship Android and Windows Phone 7 devices will also get a taste of this crystal clear call quality.
Orange begins HD Voice trial in Southern England, leaves out Buckingham Palace
Remember the good news that Orange brought to the UK on our alcohol-fueled New Year's Eve? We thought so. Anyway, it looks like said fruit company's still on course to "a new era for UK mobile communications" as it launches HD Voice trial in England today. Lucky participants across Bristol, Reading and Southampton will benefit from "crystal clear" voice calls, courtesy of the wider speech bandwidth -- 50–7000 Hz as opposed to the current 300–3400 Hz. Sadly, Orange isn't keen on dishing out deets about the special hardware, but our friends over at What Mobile had the chance to play with a modified Nokia X6 from yesterday's demo -- "It was like listening to AM radio and then switching over to listen to a CD." If all goes well, we'll meet the rest of the gang when HD Voice is rolled out "before the end of the summer." Press release after the break.
Orange plans to bring 'HD Voice' calls to UK next year
We've had some indication that Orange planned to expand its "HD Voice" technology beyond the hot testbed of Moldova sometime in the coming year, and it looks like the carrier is now starting to get a bit more specific about when the UK will finally have an alternative to standard definition calls. Apparently, Orange will begin trials of the new and improved, 3G-facilitated service early in the new year, and fully roll it out along with a "range of handsets" before the end of the year. Just what can you expect from HD voice? Why, it will make it "sound as if callers are actually in the same room," according to Orange UK chief executive Tom Alexander, who further added that "HD voice really does inject a level of innovation into mobile phone calls," and that "once people have tried it, they won't want to go back." Update: Orange has now pushed out a press release further confirming that trials will begin in the UK early in the new year, with a nationwide rollout due "later in 2010." In related news, DigiTimes is reporting that Foxconn has landed large orders for Android-powered handsets from Orange, although Foxconn itself has issued something of a denial on the matter.
Orange introduces 'HD Voice' calls -- 3G, Moldovian citizenship required
You may not have realized it, but all of the cellphone calls you've been making have totally not been HD. While we may still be stuck with our old standard def calls for a while yet over here, it looks like the good citizens of Moldova have now finally vaulted into the future courtesy of Orange, which recently made the very first "HD Voice" call in the country (on 09/09/09, of course). Overused acronyms aside, the calls do indeed appear to be of noticeably better quality (at least if the web demo is any indication), which is mostly due to their use of the new Adaptive Multi Rate - Wide Band (or AMR-WB) codec that takes advantage of the greater bandwidth afforded by 3G. Unfortunately, it looks like the HD Voice-ready handset options are a bit limited to start with (just an Orange Moldova-exclusive version of the Nokia 6720), but it looks like more phones are expected to become available as Orange expands the service throughout Europe over the course of 2010.[Via GSM Arena, thanks Sathish]
